Duo gunners

Co-op run and gun. Blast through the waves and beat the boss. Grab spread and rapid fire crates along the way.

How to play Duo gunners

Duo gunners is a two-player co-op run and gun, also playable solo. Each player runs, jumps and shoots through waves of enemies toward a boss. Use your movement keys to run and jump and your fire key to shoot. Grab power-ups like spread and rapid fire to boost your blaster. Work together to cover both sides of the screen, revive the pressure on tough enemies, and survive each wave. Clear all the waves and take down the boss to win the round.

Tips

Split the screen, one player covers the front, the other the back
Share power-ups, a spread gun on each side clears waves twice as fast
Keep moving so enemy fire cannot pin you in a corner
Focus the boss together once the last wave is clear
